To all 'whom t may concern:

Be it known that I, JESSE C. KELLY, a citizen of the United States ofAmerica, and resident of Madison Place, in the county of Hamilton andState of Ohio, have invented a new and useful Improvement inHydrocarbon-Oil Vaporizers and Burners,` of which the following is aspecification.

My invention relates to the class of burners intended to vaporize coaloil and to burn the vapors.

An object of my invention is a burner of the class described, that willafford a uniform supply of vapors at the ignition port.

Another object of my invention is an oil vaporizer and burner that maybe readily installed in an ordinary coal stove.

Referring to the accompanying drawings, in which like parts areindicated by similar reference letters;

Figure 1 is a longitudinal sectional view of the fire pot of an ordinarycoal range and a perspective view of a burner embodying my inventioninstalled therein.

Fig. 2 is a longitudinal sectional view of a vaporizerv and burnerembodying my invention.

Fig. 3, is a transverse central sectional view of the fuel admissionvalves and valve casing upon an enlarged scale.

Fig. 4 is a 'detail elevation of one of the vapor spreaders.

Fig. 5 is a sectional view taken upon line 5 5, of Fig. 2.

rIhe fuel such as coal oil, is to be stored in a tank which is elevatedabove the level of v my vaporizer and burner and is to be led thence bya fuel pipe A to the casing B of a check valve b, whence it passes tothe casing- C of admission valvesc and c. From the valve casing C thefuel is led by pipes D D to vaporizing. pipe sections E and E. thenceinto vapor chambers G and G which have ignition ports g and g', whichdirect the vapors against the spreaders H and H which are suspendedabove the ignition ports.

Check valve b is seated by gravity over the end of fuel pipe A, and hasa valve stem b', which is guided by a spider b2, so that the valve Z)may be raised by the inward flow of the coal oil, except when thepressure in the vaporizing pipe section is such as to overcome thepressure of the inflowing fuel, at which time the back pressure willseat the Letters Patent.

check valve b, and prevent the formation of air or vacuumpockets in thefuel pipe.

Each vaporizingpipe section consists of a vertical portion e and returnbend c', a horizontal portion c2, which extends above the .vaporizingchamber G, and a U bend e which enters thevalve chamber G near its topso as to leave below the pipe c3 a sediment portion g2. y

Chamber G has a tapered top gr3 which surrounds the ignition port g andforms a seat for needle valve g* which has screw threaded connectionswith the bottom of the vapor chamber, and terminates in a square end g5which may be engaged by a wrench for the purpose of regulating theposition of the needle valve.

Spreader H is preferably circular in form and has a curved surface hwhich assists in spreading the vapors and carrying them into contactwith the walls of the vaporizing pipe section. Spreader H is suspendedfrom portion e2 of the pipe by a hook h so that it may be readilyremoved therefrom when it becomes coated with carbon. The pipe sectionsD D are preferably secured in a casing K, in which7 beneath the va'porchambers I preferably support sheets of asbestos m m located in shallowpans M M suspended within the casing. The casing is preferably of theshape shown in Fig. 5, in which the side walls converge toward the top.This permits the air to be drawn toward the burners and to be dischargedthrough the opening K K2 in the top of the casing adjacent to theburners, where the oxygen may be picked up by the gas issuing fromignitionl ports gV g and projected therewith against spreaders H H tocause the mixture to burn with a blue iiame.

The vaporizer and burner embodying my invention may readily be installedin the fire pot of an ordinary coal range, by supporting the casing Kupon the grate bars thereof and so that the vaporizinc: chambers G Gcome below the stove lids N and N', the fuel door of the range beingremoved and the V-fuel pipes D D extending through the fuel door space.

In operation:

y The valve c or c which controls the burner which is to be ignited, isopened slightly so that oil will enter the valve chamber and iow out ofthe' ignition port g on to the asbestos M M. The admission valve is thenclosed and the fuel upon the asbestos is ignited. The heat from thisfire will vaporize the oil in the vaporizing chamber G. As soon as theoil in the vapor chamber has been vaporized the vapors Will burn with abluish llame around the ignition port. lVhen this occurs the admissionvalve c is opened to an extent such as to get the height of flamedesired at the burner. Then the heat from the flames of the vaporsignited at the ignition port will continue to vaporize the fresh fuel asit'reaches the vaporizing pipe section. Should the pressure in thevaporizing pipe section become so great as to cause the pressure in thepipe/section D to overcome the pressure in the fuel pipe A, the checkvalve B will be seated by its gravity and will thus prevent any vaporsbacking into the fuel pipe A, and thus Will prevent the formation of airpockets, which might otherwise flare up when they reach the ignitionport and cause the extinction of the flame at that point.

What I claim is:

In an oil burner the combination of a vapor chamber having a taperedtop, a central ignition port in the top, a needle valve extendingadjustably through the base of the chamber adapted to close upon theignition port7 a vaporizing pipe section entering the vapor chamberadjacent the top thereof and curving thence upward and having ahorizontal portion extending over the ignition port, a spreadersuspended removably from said horizontal portion of the pipe over theignition port and adapted to direct the flames from the ignition portagainst the vaporizing pipe section, a fuel pipe connected with thevaporizing pipe section, and an admission valve in the fuel pipesection.

In testimony whereof I have hereunto subscribed myname this 17th day ofMay,

JESSE C. KELLY. Witnesses:
